All of it!

A VCR runs on normal home voltage (120 volts). The voltage drop through the VCR is equivalent to the home voltage.

If you're requesting how much power the VCR uses, this is depended on the the VCR - make, model; and whatever the VCR is doing (playing? rewinding? sitting idle? paused? etc.).

The best way to find out is to buy a simple power meter. these are available for about 20 bucks.

ANSWER: SCR does not run or use home voltage. The SCR can control the load power that is where the usage is. To run a fan at different speed to dim the lights and so fourth.

It is a 4 layer diode the current passing trough to the load is the only consideration of the device requirements.

What is the electric field voltage equation and how is it used to calculate the electric field strength at a given point in space?

The electric field voltage equation is E V/d, where E is the electric field strength, V is the voltage, and d is the distance between the charges. To calculate the electric field strength at a given point in space, you can use this equation by plugging in the values of voltage and distance to find the electric field strength.


How much voltage does an electric iron takes?

Electrical devices are built to work with the voltage in your home. All electrical devices use the same voltage, which is either somewhere around 110 V (in some regions) or somewhere around 220 V (in others). Please note that "voltage" is not the same "power", the measure of how fast energy is used. Power (in watts) is basically the product of voltage (in volts) and current (in amperes). Different devices use the same voltage; but devices that use a lot of power (such as electric irons, or showers) use more current.

Can a DT830 digital multimeter measure voltage on an electric fence?

Yes, a DT830 digital multimeter can measure voltage on an electric fence, provided the voltage is within the multimeter's range. However, keep in mind that electric fences often use pulsed DC voltage, which may not be accurately displayed by the multimeter if it is not designed to measure pulsed signals. Additionally, safety precautions should be taken when working with electric fences to avoid electric shock. Always ensure the multimeter is set to the correct voltage setting before measurement.
